We divide 878620 by 9
We want to figure out the number of times 878620 can be divided by 9.

Going ahead to step 1:
9 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 9

Advancing to step 2:
9 can be fit into 87 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 81 from 87 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 9

Let's proceed to step 3:
9 goes into 68 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 5 after subtracting 63 from 68.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 9

Moving on to step 4:
56 divided by 9 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 976.0
If we subtract 54 from 56, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 9

Step 5:
When dividing 22 by 9, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 9762.0
If we subtract 18 from 22, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 9

Moving on to step 6:
When dividing 40 by 9, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 97624.0
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 97624.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 9, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 97624.44
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 97624.44 with a remaining 0.004.
